Dissociation and interpersonal autonomic physiology in psychotherapy research: an integrative view encompassing psychodynamic and neuroscience theoretical frameworks

Interpersonal autonomic physiology is an interdisciplinary research field, assessing the relational interdependence of two (or more) interacting individual both at the behavioral and psychophysiological levels. Despite its quite long tradition, only eight studies since 1955 have focused on the interaction of psychotherapy dyads, and none of them have focused on the shared processual level, assessing dynamic phenomena such as dissociation. We longitudinally observed two brief psychodynamic psychotherapies, entirely audio and video-recorded (16 sessions, weekly frequency, 45 min.). Autonomic nervous system measures were continuously collected during each session. Personality, empathy, dissociative features and clinical progress measures were collected prior and post therapy, and after each clinical session. Two-independent judges, trained psychotherapist, codified the interactions\u2019 micro-processes. Time-series based analyses were performed to assess interpersonal synchronization and de-synchronization in patient\u2019s and therapist\u2019s physiological activity. Psychophysiological synchrony revealed a clear association with empathic attunement, while desynchronization phases (range of length 30-150 sec.) showed a linkage with dissociative processes, usually associated to the patient\u2019s narrative core relational trauma. Our findings are discussed under the perspective of psychodynamic models of Stern (\u201cpresent moment\u201d), Sander, Beebe and Lachmann (dyad system model of interaction), Lanius (Trauma model), and the neuroscientific frameworks proposed by Thayer (neurovisceral integration model), and Porges (polyvagal theory). The collected data allows to attempt an integration of these theoretical approaches under the light of Complex Dynamic Systems. The rich theoretical work and the encouraging clinical results might represents a new fascinating frontier of research in psychotherapy

Individual differences in affective, cognitive, and neural responses to interpersonal and social motivation: Novel methodological perspectives

Research in this thesis manipulated approach motivation via social / interpersonal incentives, to measure the effects on mood and learning of social perceptions via neural, behavioural and psychometric measures, while also interrogating how these effects might be moderated by personality. Two initial studies explored whether motivational videos work as appetitive mood inductions by inducing activated affect. These studies also tested an online line bisection task as an index of left frontal activation, which putatively represents approach motivation and activated affect. On average, compared with control videos, motivational videos induced changes specific to activated affect without inducing changes in pleasant affect. However, there was considerable heterogeneity across participants in the induced mood changes, but without clear-cut relationships between these changes and personality (extraversion, neuroticism, and conscientiousness were tested as possible moderators). Line bisection was not affected by motivational videos relative to control videos. The third study replaced line bisection with an EEG measure of approach motivation (i.e., frontal alpha asymmetry, FAA). Measuring EEG itself was likely mood altering and complicated the pattern of mood changes observed. The expected mood induction effects were not found, although FAA did unexpectedly increase significantly after watching the control video. The final two studies evaluated probabilistic reinforcement learning in a social context via a novel artificial social interaction (ASI) task using on-screen faces of characters who varied in the amount of social reward (smiles) they gave. The reinforcing characters who smiled more throughout the ASI were rated as more likely to be befriended, more likeable, more extraverted, more agreeable, and less neurotic than the non-reinforcing characters who smiled less. These studies also showed that the participants extraversion, neuroticism, agreeableness, and autistic traits significantly moderated the character reinforcement effects on the social perception measures listed above. The methods used throughout this thesis show that considerable promise and solid foundations now exist for future developments in both areas of research

Empirically supported emerging and marginalized psychotherapies: Integration of non-concurrent multiple baseline design and hermeneutic single case efficacy design

According to APA division 12, at least two Randomized Clinical Trials (RCT) or alternatively nine Single Case Experimental Design (SCED) are required to be recognized as Empirically Supported Treatments (EST). Multiple baseline is the most suitable SCED in psychotherapy research because the treatment effects do not reverse after conclusion and do not require withdrawal in ABAB phases. Treatment's introduction is staggered sequentially across multiple participants, which allows the researcher to demonstrate that changes occur when treatment is introduced, simulating a waiting list. Hermeneutic Single Case Efficacy Design (HSCED) ensures time series analysis as the SCED, adding also qualitative and hermeneutic analysis that allow the recognition of bidirectional linkage between outcome and process variables. Furthermore, external judges assess the quality of the studies providing a verdict of good, mixed or poor outcome. To present systematic replication of multiple non-concurrent baseline HSCED as a way to empirically support both emerging and marginalized models of psychotherapy. After a phase of assessment and the collection of a stable three-point baseline, change in a convenience sample of five patients was tracked with quantitative (PHQ9, STAI, CORE-OM, PQ) and qualitative (HAT, CI) measures. Hermeneutic analysis and judge evaluation were conducted according HSCED protocol. Quantitative data show Clinical Significant and Global Reliable Change in all patients, supported by qualitative data. Hermeneutic analysis suggests specific outcome-to-process linkage and therapeutic interventions followed by shift in weekly outcome measures, supporting and refining the theoretical predictions of the manualized Intensive Transactional Analysis Psychotherapy. Combining multiple baseline design and HSCED, it is possible to support recognition as EST of emerging and marginalized treatments, involving less resources than RCT

Eye quietness and quiet eye in expert and novice golf performance: an electrooculographic analysis

Quiet eye (QE) is the final ocular fixation on the target of an action (e.g., the ball in golf putting). Camerabased eye-tracking studies have consistently found longer QE durations in experts than novices; however, mechanisms underlying QE are not known. To offer a new perspective we examined the feasibility of measuring the QE using electrooculography (EOG) and developed an index to assess ocular activity across time: eye quietness (EQ). Ten expert and ten novice golfers putted 60 balls to a 2.4 m distant hole. Horizontal EOG (2ms resolution) was recorded from two electrodes placed on the outer sides of the eyes. QE duration was measured using a EOG voltage threshold and comprised the sum of the pre-movement and post-movement initiation components. EQ was computed as the standard deviation of the EOG in 0.5 s bins from –4 to +2 s, relative to backswing initiation: lower values indicate less movement of the eyes, hence greater quietness. Finally, we measured club-ball address and swing durations. T-tests showed that total QE did not differ between groups (p = .31); however, experts had marginally shorter pre-movement QE (p = .08) and longer post-movement QE (p < .001) than novices. A group × time ANOVA revealed that experts had less EQ before backswing initiation and greater EQ after backswing initiation (p = .002). QE durations were inversely correlated with EQ from –1.5 to 1 s (rs = –.48 - –.90, ps = .03 - .001). Experts had longer swing durations than novices (p = .01) and, importantly, swing durations correlated positively with post-movement QE (r = .52, p = .02) and negatively with EQ from 0.5 to 1s (r = –.63, p = .003). This study demonstrates the feasibility of measuring ocular activity using EOG and validates EQ as an index of ocular activity. Its findings challenge the dominant perspective on QE and provide new evidence that expert-novice differences in ocular activity may reflect differences in the kinematics of how experts and novices execute skills

Cross-cultural evidence for the influence of positive self-evaluation on cross-cultural differences in well-being

Poster Session F - Well-Being: abstract F197We propose that cultural norms about realism and hedonism contribute to the cross-cultural differences in well-being over and above differences in objective living conditions. To test this hypothesis, we used samples from China and the United States. Results supported the mediating role of positive evaluative bias in cross-cultural differences in well-being.postprin
